registerXSLTExtension: Register a new XSLT extension namespace

Description

This function allows the R programmer
to declare a new XSLT extension namespace.
One can either register functions for this extension
in this call or via subsequent direct
calls to registerXSLTFunctions.

Usage

1

Arguments

ns

the namespace's URI. This can also be given
in the form c(prefix = "http:...") and then
the value of prefix can be used to identify
the extension in calls to
registerXSLTFunctions via its .namespace
parameter.

...

name = function pairs of functions that are to be
registered for this XSL extension and made available each time
an XSL processor is activated.

.funcs

this is an alternative form of specifying
the collection of name = function pairs
which is more convenient when these functions are already in list
form.
The ... approach is useful for "interactive" use, i.e.
when the functions are known when the command is written.

Value

TRUE! It is the side-effect of creating
a registry for this namespace that it is of interest.
